This invention relates to mixing devices and more particularly ,toahouseholdmixer for mixing maltedumilk drinks and the like.

A main Vobject of the invention is t provide a novel and improved mixingdevicefof simple construction adapted to be mounted o'n the rim ,cfacontainer'su/ch as a milk bottle and including means for drawing airinto the container for mixing with the liquids contained therein duringthe agitation of said liquids Aby the device.

A further Lobject of the invention is to provide an improved mixingdevice having components which are simple in structure and which areextremely easy to manufacture and assemble, and including means forresiliently mounting the device on the rim of a standard milk bottle orsimilar standard container in sealing relation thereto.

Other objects and advantages of the invention will appear from thefollowing description and claims and from the accompanying drawings,wherein:

Figure 1 is an elevational View, partly in crosssection of a milk bottleupon which is mounted a mixing device in accordance with this invent on.

Figure 2 is a cross-sectional view taken on line line 2-2 of Figure 1.

Figure 3 is a top view of the mixing device employed in Figure 1.

Referring to the drawings, designates a moulded body of rubber orsimilar elastic material formed to be tightly tted over the rim of amilk bottle |2 in gripping relationship therewith. Body is provided withtab members I3, I3 adapted to be grasped by the operator in mounting thedevice on the bottle or removing the device from its mounted position onthe bottle.

Body is formed with an integral upstanding sleeve I4 in which acylindrical metal sleeve I5 is positioned. Rotatably mounted in bodycentrally thereof is a depending vertical tubular member I6 formed witha helical flange I1. The top end of tubular member I6 is formed with abevel gear I8 integral therewith which rests on a washer I9. Washer I9serves as a bearing member for rotataby supporting bevel gear I8 andtubular member I6 axially with respect to body II, the central part ofthe gear being open to permit passage of air downward through the tubeinto the bottle.

Meshed with bevel gear I8 is a vertical bevel gear 20 carried on ahorizontal shaft 2| projecting laterally through sleeve I and sleeve I4.Shaft 2| is formed with a square end for releasable engagement with acrank member 22. Shaft 2 claims. (c1. 259-1705) 2| is .rotatablysupportedin a metal bearing washer 23 carried by sleeve I.,4 and isformed with an integral spacing collar 24.

Positioned axially in tubular membr It is a shaft 25 which Vcarries atits bottom end an agitator vane 26 formed of a wire loop having crossbars 2l secured thereto. Adjacent its upper `end rod 25 is rotatablymounted in a bearing 25' and. has mountedthereon a lbevel gear 28 whichmeshes with the bevel gear 26. Above bevel gear 2 8, rod' 25 carries afan member 29 adapted to circulate air into tubular member I5 throughthe opening in the central part of the gear 28 when rod' 25 is rotated.The top end of rod 25 carries a chuck collar 3U for at times couplingthe rod to a power device such as an electric motor.

When the mixing device is actuated either by manual rotation of crankmember 22 or by power actuation of shaft 25, tubular member I6 isrotated in one direction and agitator vane 2B is rotated in the oppositedirection. At the same time air is blown into the bottle I 2 by fanmember 29, through the tube I6 and with the air escaping from the bottlethrough openings 3| in the cap I I. The liquids in the bottle are thusagitated and thoroughly mixed with air, producing a desired aeratedmixed drink, such as a malted milk drink when the proper ingredientstherefor are employed. Of course, other aerated liquid mixtures may beproduced by the device if desired.

spilling of liquid during the mixing process is prevented by resilientbody I which embraces the bottle rim in sealing relation thereto.

While a specic embodiment of a mixing device has been disclosed in theforegoing description, it will be understood that various modificationswithin the spirit of the invention may occur to those skilled in theart. Therefore it is intended that no limitations be placed on theinvention other than as defined by the scope of the appended claims.

What is claimed is:

l. In a mechanical mixer for mixing elements in an open top container, acap adapted for being removably positioned upon said open top container,said cap having openings extending therethrough from the exteriorsurface thereof to communicate with the interior of said container, asleeve carried by the top of said cap, a shaft mounted in said sleeveextending into said container, an agitating element on a portion of theshaft extending into said container, a tubular member surrounding asubstantial portion of said shaft mounted in said cap and extending intosaid container, agitating means on the portion of said tubular memberextending into said container, a rotating element on said tubular memberpositioned Within said sleeve and spaced above said cap, said rotatingelement having an opening therein communicating with the interior ofsaid tubular member, a rotating element on the shaft within said sleevepositioned above and spaced from the rotating element on said tubularmember, a rotative element mounted in said sleeve and operativelyconnected with the rotating elements on said shaft and tubular memberrespectively adapted to rotate said elements in opposite directions, aian on the shaft positioned within said sleeve above and spaced from therotating element on the shaft adapted for feeding air downwardly throughthe tubular member and into the elements being mixed in the container,and means for rotating said rotative elementffrom the exterior of saidsleeve.

2. In a mechanical mixer for mixing elements( in an open top container,a cap adapted for being removably positioned upon said open topcontainer, said cap having openings extending therethrough from theexterior surface thereof to communicate with the interior of saidcontainer, a sleeve carried by the top of said cap, a shaft mounted insaid sleeve extending into said container, an agitating element on aportion of the shaft extending into said container, a tubular membersurrounding a substantial portion of said shaft mounted in said cap andextending into said container, agitating means on the portion of saidtubular member extending into said container, a gear on said tubularmember positioned within said sleeve and spaced above said cap, saidgear having an opening therein communicating with the interior of saidtubularmember, a gear on the shaft within said sleeve positioned aboveand spaced from the gear on said tubular member, a gear rotativelymounted in said sleeve and meshing with the gears on said shaft andtubular member respectively adapted to rotate said gears in oppositedirections, a fan on the shaft positioned within said sleeve above andspaced from the gear on the shaft adapted for feeding air downwardlythrough the tubular member and into the elements being mixed in thecontainer, and means for rotating said rotative gear from the exteriorof said sleeve.
